This particular dishidia is native in my region and easily grows on tree branches and often times appear to cascade and hang from tree branches. I often find them growing vertically on tree barks. They are not very common compared to the
Dischidia Nummularia commonly known as String Of Nickels
are not known to be cultivated as an ornamental plant here unless it a variegated one.
The name itself String Of Nickels is similar to what the locals call it here as duit-duit but often confused with another fern species: Dragon scale Fern (Pyrrosia piloselloides) which can be invasive and fatal to some trees.
These are collected from the nearby trees around my region for cultivation purpose but I can say it does prove difficult compared to most dischidia species.
However, just like most dischidia - the care and cultivation very much similar with hoya and other epiphyte plants.
This require a fast draining medium - something like orchid medium mix.
It does well with a mixture of perlite, sphagnum moss, cocopeat & bark mix.
It should not be a strong drainage mix where it doesn't hold any moisture at all but it should not be holding water too where the roots and stem can rot too. The balance of both is ideal.
Sometimes the nursery plant them - rolling them in a coconut husk making a ball from it. Another medium will be coconut husk stuffed inside a seashell with the dischidia hanging from it.
For sometime - it would look cool but eventually it get spend and burned due to lack of root growth and nutrients - making the plant leggy and trying to escape elsewhere.
I water daily and twice during the hot dry days. These can go without water for few days to a week and perhaps you have to take note on how the foliage appearance - if it appears withered or drying than watering is mandatory. The downside of watering will cost the leaves to turn yellow and start rotting - therefore - the right balance is necessary.
Dischidia is not a totally shade loving plant but you can place them in bright indoors area. I for one had experience where when it is placed in dark areas - they rarely show new growth and appears to be very leggy (the leaves nodes along the stem appear to phase out far apart and it is very unsightly especially when you prefer to have a compact foliage plants)
These are trailing plant and more on the wild side. The seemed to do well in most unforgiving conditions but at times - just barely surviving and it is indeed a slow growing plant - so don't expect much if you received a small cuttings and looking forward for new growth - It may take many months to actually notice anything.
I for one, just place them in their ideal spot and consider that done there and routinely water them on daily basis and weekly spray flowering fertilizer on them hoping them to bloom. Otherwise, it's another trailing foliage plant that I'm contented with.
1) Do take effort to foliar fertilizer on them to induce new growth or else it will remain in that same size for months.
2) It's a trailing plant - so do allow space for it to grow and trail heavy, it will climb and vine everywhere - so do take note on that garden space in place them permanently as once it captured and coiled within the garden space - it will be difficult to remove them without cause damage to the vine or foliage.
3) This plant does produce aerial roots and may start off new shoots hence a new plant from a different location where it had rooted. You can propagate new plants from here but do it soon or if in case it had established itself - it would be too difficult to remove them without damaging them.
